Theinyention relates to operating devices for flushing tanks and more particularlyg in connection with vitreous or porcelain tanks}. lVith suchtanks it is desirable tolforn r jtlie operating'h'andle 'alsoofvitr eous material.

This, however, involves certain difficulties in construction and it is the object of the present invention to overcome such difliculties as hereinafter set forth.

In the drawings:

' Figures 1 and 1 are perspective views of the vitreous operating handle and the shank therefor detached. I

' Figure 2 is a longitudinal section through the handle showing the manner of embedding and securing the shank.

Figure 3 is a cross section through the wall of the tank in the plane of the'operating handle and shank.

Figure t is an elevation from the inside of the tank showing the stop for the operating handle.

A is the wall of the porcelain tank through which the operating shank passes. This wall preferably has an aperture for the shank formed therethrough with the casting or formation of the tank. It is usual to line this aperture with a bushing having a collar or shoulder at one end and a clamping nut t engaging the threaded portion at the opposite end. I have simplified the construct tion by using a comparatively thin metal tube B the opposite ends ofwhich are flared or flanged outward at C, without producing any portion projecting beyond the outer face of the tank. This permits of placing the operating handle flush with the wall of the tank without interference.

The vitreous handle D is preferably formed hollow as shownin Figure 2 and is provided on its inner side with an aperture E for the entrance of the shank. It is desirable to firmly attach this shank to the handle so that it will not become loosened by the stresses incident to operation, these being chiefly torque stresses. I have accomplished such result by forming the shank F with a head portion G provided with a laterally projecting tapering arm which will expand within the hollow body centrally between and substantially parallel to the opposite walls thereof. The shank also preferably has a thin collar or flange H for closing the aperture E. Thus by filling the hollow body with cement and embedding the head therein a very strong attachment is obtained.

y Itis usual to operate thehandle by ;rock-. ingthe-same iii eithergdirection but to limit the angle of movement by suitable stops. In my construction the limiting stops are formed by projecting arms I, I on the hub' J of the operating lever K within the tank. The hub J is secured to the shank F by a pin or screw L and the arms I, I are adapted to engage with a stop on the tank such as the cover M. As the striking ofthe rigid arms l against the tank will produce noise I have avoided such noise by providing a cushioning means. This, as shown, comprises a resilient metal strip N which lies close to and substantially parallel with the arms I and is attached to the hub J by lugs or projections 0 turned over the same.

Thus in operation the yielding strip N first contacts with the stop and cushions the further movement of the arms I so as to avoid noise.

With the construction as described it would be obvious that the handle may be assembled with the tank by inserting the shank F through the bushing B and then attaching the hub J and lever K to the end of the shank.

What I claim as my invention is:

1. An operating device for flushing tanks comprising a hollow vitreous handle, a metallic shank therefor having 'an arm pro jecting laterally within said hollow body anda cementitious filling for said hollow body in which said arm is set.

2. An operating device for flushing tanks comprising a hollow vitreous handle having an entrance aperture on its inner face, a shank having the head portion inserted through said entrance aperture and provided with an arm for extending longitudinally within said body radially from said shank, said shank also having a collar or flange for closing said aperture and a cementitious filling in said hollow body in which said head and arm are embedded 3. In an operating device for flushing tanks the combination with a vitreous tank having an aperture through the wall thereof, of a thin wall metallic tube passing through said aperture and flared at its opposite ends to prevent disengagement from said wall without projecting beyond the outer face thereof and a shank for the operating device passing through a bushing formed by said tube.

4. In an operating device for flushing tanks the combination with an apertnred.

tank Wall, an operatinghandle, a shank for said handle passing through the aperture in said Wall and a lever attached to said shank Within the tank, of a stop mechanism for limiting the angular movement of said handle comprising a radially projecting arm on said shank, a shoulder on said tank for engaging said arm and a resilient strip secured to said arm and slightly spaced therefrom for Cushioning its impact against said stop.

- dially projecting arms secured to the shank,

a shoulder on the tank for engaging said arms and a resilient strip secured to said arms slightly spaced therefrom for cushioning the impact against said stop.

In testimony whereof I affix my signature.
